Biological parameters of the egg parasitoid Trissolcus grandis (Hym.: Scelionidae) on Eurygaster integriceps (Hem.: Scutelleridae)
زنبور Trissolcus grandis Thomson، مهم‌ترین پارازیتویید انفرادی تخم سن گندم،Eurygaster integriceps Puton، است. بااین‌که این حشره دارای پراکنش وسیعی در ایران می‌باشد، اما غالباً نقش آن نادیده گرفته شده است. هدف از این بررسی تعیین ویژگی‌های زیستی و بهینه‌سازی روش پرورش این پارازیتویید به‌منظور کاربرد آن در برنامه‌های کنترل بیولوژیک سن گندم بود. میزان پارازیتیسم زمانی‌که نسبت میزبان- پارازیتویید 1:...

trissolcus grandis thomson is a solitary egg parasitoid of sunn pest, eurygaster integriceps puton. although widely distributed, it has often been overlooked in field surveys. our objectives were to develop an efficient rearing technique for t. grandis, and to determine the basic bionomics and demographic parameters, necessary for future augmentative biological control programs. exposure of 0-4...

insects are poikilothermes, hence environmentalfactors, and primarily temperature can affect their biological activities and behavior. in this study thermal range preferred by ooencyrtusfecundusferrier &voegelewas; investigated by a device producing a thermal gradient from 16 to47ºc. temperature of different parts of the arena was precisely recorded by eight thermometers entered the arena from ...
